Overview of this book

Want to get started with impressive interactive visualizations and implement them in your daily tasks? This book offers the perfect solution-D3.js. It has emerged as the most popular tool for data visualization. This book will teach you how to implement the features of the latest version of D3 while writing JavaScript using the newest tools and technique You will start by setting up the D3 environment and making your first basic bar chart. You will then build stunning SVG and Canvas-based data visualizations while writing testable, extensible code,as accurate and informative as it is visually stimulating. Step-by-step examples walk you through creating, integrating, and debugging different types of visualization and will have you building basic visualizations (such as bar, line, and scatter graphs) in no time. By the end of this book, you will have mastered the techniques necessary to successfully visualize data and will be ready to use D3 to transform any data into an engaging and sophisticated visualization.

Thinking about data functionally


I've mentioned previously that D3 is very functionally designed, meaning that it uses some of the idioms JavaScript has adopted from functional programming. Although we can still approach D3 development in a very classical, object-oriented fashion, our lives will be much easier if we start thinking about our code and data with a functional mindset.

The good news is that JavaScript almost counts as a functional language; there are enough features to get the benefits of a functional style, and it also provides enough freedom to do things imperatively or in an object-oriented way. The bad news is that, unlike real functional languages, the environment gives no guarantee about our code.

Note

Later on, in Chapter 9, Having Confidence in Your Visualizations, we'll look at TypeScript, which allows compilation of JavaScript using static types, and Tern.JS , which analyzes code in order to improve tooling. These efforts go a great deal toward improving confidence in...
